Description
15 20 25 30 35 452 771 2 häftande sida när det är upprullat, varigenom rullens olika lindningsvarv kan förskjutas relativt varandra. 15 20 25 30 35 452 771 2 adhesive side when wound up, whereby the different winding turns of the roll can be displaced relative to each other.
För att undgå denna serpentineffekt, som uppstår spe- ciellt med smalare remsor, och för att åstadkomma en snab- bare utläggning av listerna, har man försökt att fast an- bringa en exempelvis silikonbehandlad plastfolie på den sida av tätningsmaterialet som ej är försedd med självhäf- tande lim. Genom detta förfarande har man automatiskt upp- nått släppning mellan den självhäftande ytan och materia- lets med silikoniserad plastfolie försedda baksida, sam- tidigt som ändå en viss vidhäftning uppstår så att inte rullen faller isär vid hantering. En på detta sätt fast anbringad oexpanderad silikoniserad plastfolie har dock den nackdelen att dess yta inte blir så flexibel och följ- sam som önskvärt. Om materialet sammanpressas i en punkt eller böjes, så bildas veck i folien med försämrad tät- ningsförmåga som följd.In order to avoid this serpentine effect, which occurs especially with narrower strips, and to achieve a faster laying of the strips, an attempt has been made to attach a, for example, silicone-treated plastic foil to the side of the sealing material which is not provided with self-adhesive. - tooth glue. Through this method, release has been achieved automatically between the self-adhesive surface and the back of the material provided with siliconized plastic foil, at the same time as a certain adhesion still occurs so that the roll does not fall apart during handling. However, an unexpanded siliconized plastic foil fixed in this way has the disadvantage that its surface does not become as flexible and compliant as desired. If the material is compressed at one point or bent, folds are formed in the foil with a reduced sealing ability as a result.
Uppfinningen har till uppgift att möjliggöra snabb och smidig montering av dylika tätningslister samt att åstadkomma en praktisk och ekonomisk tätningslistartikel utan att hittills kända tätningsremsors positiva egenskaper går förlorade.The object of the invention is to enable quick and smooth assembly of such sealing strips and to provide a practical and economical sealing strip article without the positive properties of hitherto known sealing strips being lost.
Detta uppnås enligt uppfinningen genom användning av speciell ytbehandling, sådan den kännetecknas i patent- kravet l.This is achieved according to the invention by using special surface treatment, as characterized in claim 1.
Vidare föreslår uppfinningen en sålunda tillverkad tätningsremsa av flexibelt cellmaterial, företrädesvis skum- gummi eller cellpolyeten, vars ena sida uppvisar ett själv- häftande limskikt och vars andra sida har behandlats med ett silikonpreparat eller annat släppmedel, som förhindrar vidhäftning mot det självhäftande limmet vid upprullning av materialbanan och kännetecknas av de i patentkravets 6 kännetecknande del angivna särdragen.Furthermore, the invention proposes a sealing strip made of flexible cell material, preferably foam rubber or cell polyethylene, one side of which has a self-adhesive adhesive layer and the other side of which has been treated with a silicone preparation or other release agent, which prevents adhesion to the self-adhesive adhesive. the web of material and is characterized by the features stated in the characterizing part of claim 6.
Lämpliga vidareutvecklingar och utföringsformer fram- går av underkraven 7-9.Suitable further developments and embodiments are set out in subclaims 7-9.
Det är i och för sig i andra sammanhang känt att yt- behandla plastbanor för att uppnå olika effekter, bl a för 10 15 20 25 30 35 452 771 3 att underlätta vidhäftning av vissa påförda preparat. Så- lunda har man redan tidigare ytbehandlat plastfolier för att göra deras yta bättre tillgänglig för därpå följande förädling eller annan vidarebearbetning. Exempelvis är det genom US-A-l 416 357 känt att behandla ytor med primer, medelst flambehandling eller genom s k koronabehandling.It is per se known in other contexts to surface-treat plastic webs in order to achieve various effects, among other things for facilitating adhesion of certain applied preparations. Thus, plastic foils have already been surface-treated before to make their surface more accessible for subsequent processing or other further processing. For example, it is known from US-A-1,416,357 to treat surfaces with primer, by means of flame treatment or by so-called corona treatment.
Vidare är det känt att koronabehandla polyetenfolie innan den tryckes med exempelvis reklamtext. Koronabehandling innefattar att olika material utsättes för elektriska gnis- tor vid urladdning av statisk elektricitet, varvid på ytan anses uppkomma molekylära partiklar, vilka gör att man kan vidarebearbeta ytan med tryckfärger, lim eller liknande.Furthermore, it is known to corona treat polyethylene foil before it is printed with, for example, advertising text. Corona treatment involves exposing various materials to electric sparks when discharging static electricity, whereby molecular particles are considered to appear on the surface, which means that the surface can be further processed with printing inks, adhesives or the like.
Man får då en kemisk förening med materialet och kan där- med få en varaktig vidhäftning, även vad gäller material med inbördes ganska olika fysikaliska egenskaper.You then get a chemical compound with the material and can thus get a permanent adhesion, even in the case of materials with relatively different physical properties.
Det är vidare känt (DE-A-2 254 422) att behandla olika ytor med släppmedel för att undvika vidhäftning, speciellt vad gäller vidhäftning mot självhäftande lim, varvid oftast silikonbehandling tillgripes.It is further known (DE-A-2 254 422) to treat different surfaces with release agents in order to avoid adhesion, especially with regard to adhesion to self-adhesive adhesives, in which case silicone treatment is most often used.
Genom kombination av de båda ovannämnda åtgärderna - dels ytbehandling för att underlätta vidhäftning, dels släppmedelsbehandling - uppnås kombinationseffekten att det tidigare erforderliga skyddsmaterialet, vars borttagande ofta blir tidsödande, icke längre behöver användas. Detta både förenklar och förbilligar i sin tur produktionen och underlättar användningen och icke minst hanteringen. Dess- utom vinnes den effekten att enligt uppfinningen tillver- kade upprullade tätningsremsor hâlles samman genom den be- gränsade vidhäftning som ändå uppstår mellan den t ex sili- konbehandlade ytan och den självhäftande ytan, varigenom den tidigare uppkommande, icke önskvärda s k serpentin- effekten elimineras. Därigenom uppnår man inte bara att rullarna betryggande hålles ihop utan man kan tillverka större rullar än tidigare och dessa rullar håller ändå ihop.By combining the two above-mentioned measures - surface treatment to facilitate adhesion and release treatment - the combination effect is achieved that the previously required protective material, the removal of which often becomes time-consuming, no longer needs to be used. This in turn simplifies and reduces the cost of production and facilitates use and not least handling. In addition, the effect is gained that according to the invention rolled-up sealing strips are held together by the limited adhesion which still arises between the eg silicone-treated surface and the self-adhesive surface, whereby the previously occurring, undesirable so-called serpentine effect is eliminated. . This not only ensures that the rollers are held together securely, but that larger rollers can be manufactured than before and these rollers still hold together.
Det nya tillvägagângssättet vid framställning av nämnda tätningslister kan tillämpas både när den expanderade cell- 452 771 4 plastbanan, företrädesvis cellpolyetenbanan, som exempelvis kan ha en tjocklek mellan l och 4 mm och en bredd av 1000 till 2000 mm, efter upprullning skäres till smalare rullar med en enda stor cirkelkniv eller när materialbanan löpande delas med mindre knivar eller andra skäranordningar och de därvid skurna remsorna spolas upp på s k bobiner i mycket långa längder, varvid ett större antal lindningsvarv kan upprullas i och med att bobinen vandrar i sidled fram och åter.The new approach in the manufacture of said sealing strips can be applied both when the expanded cellular plastic web, preferably the cellular polyethylene web, which may for example have a thickness between 1 and 4 mm and a width of 1000 to 2000 mm, after winding is cut into narrower rollers. with a single large circular knife or when the web of material is continuously divided with smaller knives or other cutting devices and the strips then cut are wound up on so-called bobbins in very long lengths, whereby a larger number of winding turns can be wound up as the bobbin travels sideways back and forth.
